"There were probably better ways to deal with it than synthetic cannabis ... but thinking they'd sell something like that over the counter ... you wouldn't think it would lead to something like this."
His dependence quickly grew.
"I'd just have a cone and it would ease those anxieties ... but it got to the point where I was just using it constantly all day."
Heginbotham said his heavy use changed his personality, to the point he was no longer socialising and he had lost the colour in his skin.
He was "out of his mind" when he walked into Lenz Superette with a pistol on May 27, and left with five packets of cigarettes and 253 packs of synthetic cannabis. Police caught him at a motel soon after.
He now couldn't understand how manufacturers could sell the products, describing it as "profit-mongering".
"They don't care what it's doing to people. How can they not see the outcry in their general communities?"
